I've been an avid user of ZA for many a year. Since I needed a break from this I tried Comodo, after PCTOOLS. It outperforms PCtools and ZA both. Why?
All my internet related apps are greatly speeded up! even PCtools could not do this to the extend Comodo does. I KNEW I was missing some speed but finally I found out where is was; in my firewall. even XP is starting up much faster, because Comodo doesn't hog resourses and doesn't take the time to start up like ZA does!
I'm anxiuosly looking toward their final release of their free antivirus program. If it's as good as their firewall, I'm hooked!
